Specification of Letters Patent.

Patented July it), 1917.

To all whom it may concern:

Be it known that I, HARRY SHUTTLE- won'rrr, a citizen of the UnitedStates, residing at Flint, county of Genesee, State of Michigan, haveinvented a certain new and useful Improvement in Harvesting-Ma chines,and declare the following to be a full, clear, and exact description ofthe same, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to machines for cutting bean vines or similarplants. It has for its object apparatus suitably designed to do thiscutting in an GlfiOELClOUS way.

In the drawings,

Figure 1 is a side elevation of the machine.

Fig. 2 is a plan. view of the machine.

Fig. 3 is a rear elevation of the same.

Fig. 4 is a sectional detail of a cutter and its mounting.

F ig. 5 is a detailed elevation of a modified form of cutter and itsmounting.

Fig. 6 is a plan view of one of the cutters detached from its mounting.

The machine contains a number of parts which are common in farmimplements, such, for instance, as the seat a, and the traction wheels 6capable of having their relative positions with respect to the carriageo changed by means of being journaled on bell crank arms d which arepivoted t0 the carriage 0. These bell crank arms are held in variouspositions of adjustment by reason of the catches e engaging in thetoothed segments f. A suitable tongue 9 is employed.

Depending from the front of the carriage are a pair of members 71 whoseforward ends 7' act as guides for lifting and lowering the castercarriers k. Each caster carrier is provided with a pair of rearwardlyand obliquely extending deflecting rods Z. The two pairs of deflectingrods converge toward each other at the rear. The purpose of thesedeflecting rods is to force the bean vines over to one side and awayfrom the cutters, as shown in Fig. 3.

At the rear of the carriage a pair of hangers m, one at each side, eachsupport a cutter carrier a which carries a gang of rotary cuttersprovided with serrated edges (the latter feature appearing in Fig. 6).These cutters are each provided with a hub 0 sleeved upon smalldepending shafts secured to the cutter carrier 71, the enlarged end 7)of the shaft serving to restrain the cutter from dropping off. In theform shown in Fig. 5 an expansion spring g serves to yieldingly forcethe cutter downward but "allows upward movement of the cutter whendesirable by reason of striking an obstruction. The cutters are in theform of disks that are preferably tipped only slightly from thehorizontal. The guard 9" precedes the cutter carrier to protect anddeflect obstructions.

A chain 51 connects the link t, which pivots the caster carrier Z; tothe hanger m, with the bell crank arm (Z. Hence when the handle end ofthe bell crank lever is pulled to the rear to lower the traction wheelsand thereby bring the cutters clear of the ground, which is especiallydesirable when the implement is traveling along the road to or fromwork, the caster carriage is lifted clear of the road.

The operation is as follows: The implement is preferably designed tostraddle two bean rows. The traction wheels are adjusted relatively tothe carriage to bring the gangs of cutters at the desired point ofcontact with the bean vines. The deflectors how the plants over awayfrom the cutters; The chosen point for cutting the bean vines may be atthe very point where they enter the earth or for that matter the cuttersmay dig into the bean hills and cut the roots instead of the bean stems,depending of course upon the relative positions of the traction wheelsand the cutters and the height of the bean hills above the ground uponwhich the traction wheels are traveling. The two gangs of cuttersconverge toward each other from front to rear so as to give considerablewidth to the cutting swath and at the same time deliver an obliquedrawing out which is known to be the most effective and which at thesame time rotates the cutters by reason of their serrated or toothededges.

What I claim is:

1. In a harvesting machine of the class described, the combination of acarriage, a pair of movably supported traction wheels, cutting mechanismadjustable relatively to to the traction Wheel and vice versa.

3. In a harvesting machine, the combination of a carriage c, the memberz' with its guiding surface j, the caster wheel carriage It providedwith a caster wheel, the deflector Z, the link If pivotally supported atone end, the bell crank arm d, the traction wheel I) journaled at theend of the bell crank arm, and means for connecting the link t with thebell crank arm d for the purpose of raising the caster wheel andcarriage as the traction wheel Z) is lowered.

In testimony whereof, I sign this specification in the presence of twoWitnesses.
